Answer 2

This is covered in the Python 3 training under More Type.
But, from what I understand:

-Lists use square brackets []
-Tuples use parentheses ()
-Dict use curly bracket {}

-Tuples: use to create a fixed list to reference and will not need updating. (calendar months, days of the week, names of your children after a vasectomy)
-Lists: use to create a list you may need to update. (top 10 books, countries visited, namea of your children before a vasectomy)
-Dicts: used to create a collection of unordered data that can be referenced by a key, as opposed to the indexed position used for a list. (names/ numbers in your phone, product name/ product price for inventory, name/ room number for hotels)

-Lists, creats a list of items that is indexed. Items can replaced. The list can be added to or have items deleted from.
-Tuples, are similar to lists but items cannot be edited. NO adding to, deleting or changing. (immutable) *** This is why Tuples require least amount of memory to use ***
-Dicts are data structure that has a hash table of key:value pairs. Dict is an unordered collection.
